Over 480 drivers in Wales were caught over the drink drive limit during the All Wales Winter Anti-Drink and Drug Driving Campaign.

Throughout the month-long campaign 30,718 drivers throughout Wales were breath tested.

Dyfed-Powys Police carried out 8204 breath tests with 140 being positive. In Gwent a total of 2,203 breath tests were carried out, with 42 being positive.

In North Wales Police officers tested 15,627 drivers, with 76 being positive, and South Wales Police administered 4684 tests with 230 positive results.

It is disappointing that 488 drivers throughout Wales chose to risk their own lives, and the lives of others during the campaign. We were clear in our messages throughout the campaign that drink or drug driving is not acceptable, and will not be tolerated. But those that chose to break the law and endanger themselves and other road users arrogantly were in the minority, and we thank the public that showed support for the campaign and were happy to co-operate.

Almost 20,000 people across Wales have been tested in a crackdown on driving under the influence of drink and drugs. The month long campaign by Welsh police forces saw more than 400 people arrested. Inspector Lee Ford of Gwent Police says the weather has been a temptation.

502 people around Wales tested positive for drink-driving, or failed or refused to be breath-tested, during a month-long crackdown over Christmas. That's a fall of 43 when compared with the same month a year earlier.

All four of Wales' police forces joined together in the campaign, from 1 December to 1 January. More than 35,000 motorists were tested - that's an increase of 7,700 from 12 months before.

Cardiff and Swansea are among the worst places in the UK for drink-driving, according to car insurance application figures. The comparison website moneysupermarket.com ranked them both in the top 10 after looking at recorded offences on drivers' insurance quotations.
